It can not only provide nutrients for crops directly, but also activate potential nutrients in soil and improve the content of soil available nutrients. Organic fertilizer contains a variety of beneficial microorganisms, which can enhance the activity of soil microorganisms and promote the transformation of substances in soil. Organic fertilizers play an important role in improving soil fertility. The application of organic fertilizers can improve the ability of soil water and fertilizer conservation and promote the formation of soil aggregates, thus improving soil physical and chemical properties and soil fertility. At the same time, organic fertilizers can also prevent and reduce soil pollution caused by pesticides and heavy metals. The disadvantages are: low nutrient content, slow fertilizer efficiency; large amount of fertilization, inconvenient transportation and application; in the period of exuberant crop growth and more fertilizer, it is often unable to meet the nutrient needs of crops in time. There are many kinds of organic fertilizer, such as manure and urine fertilizer, pile retting fertilizer, straw fertilizer, green manure, soil fertilizer, peat, biogas fertilizer and so on.
